Might be the flame sensor taking to long to cool down, part # 338906Seen it. The flame sensor is really a ignitor sensor. It's bi-metal within bends when heated to the point of opening contacts and killing power to the ignitor. The coils which are on the same circuit get boosted by the extra power flooding in from the now dead in the water ignitor. Gas rushes outwards and colides with that scaREAMing hot ignitor and KA wooshhhh you have igniton Houston. While those coils are most likely to be a problem that sensor can also play tricks on a gas dryer.

I tested my flame sensor with a multimeter and got a reading when cold, I put it next to a light bulb and it switched to no reading. It appears to be working ok? I tested my solenoids with a multimeter as well and every number matched what I was supposed to get, (I also have an old bad set of solenoids that I did the same test on and got the correct 'bad' results so I am assuming my solenoid testing was ok? But I also read that solenoids can't really be tested.. I also read that if they are bad then there shouldn't be a flame at all. I can't figure out what to replace on my dryer. my symptoms are the same as the OP. dryer lights with a strong flame for up to 2 minutes and then goes out, I have ran it w/o the vent connected so I am assuming my vent pipe is not clogged, I have also felt the air flow outside and it is strong. I have tested all the fuses and sensors on the back of the dryer with a multimeter and all have continuity.
